Question

Factor out the coefficient of the variable in the expression 1/3b - 1/3

Answer 1

Answer:

$\dfrac{1}{3} \left (\dfrac{1}{b} - 1 \right )$

Step-by-step explanation:

$f(x) = \dfrac{1}{3b} - \dfrac{1}{3}$

1. Find the least common multiple of the denominators

The least common multiple of 3 and 3 is 3.

2. Factor out ⅓.

$\dfrac{1}{3b} - \dfrac{1}{3} = \mathbf{\dfrac{1}{3} \left (\dfrac{1}{b} - 1 \right )}$
